A series of N-((1-benzyl-1H-1,2,3-triazol-4-yl)methyl)nicotinamides (4) was synthesized and tested for their anticancer activity against a panel of 60 human cancer cell lines. Some of the representative compounds such as 4a, 4b, 4f, 4g, 4i and 4t were selected for the five dose study and amongst them 4g and 4i displayed significant anticancer activity with GI50 values ranging from 0.25 to 8.34 and
合成了一系列N -((1-苄基-1 H -1,2,3-三唑-4-基)甲基)烟酰胺(4),并测试了它们对一组60种人类癌细胞系的抗癌活性。选择了一些代表性化合物,例如4a,4b,4f,4g,4i和4t进行五剂研究,其中4g和4i在GI 50下显示出显着的抗癌活性。值分别为0.25至8.34和1.42至5.86μM。细胞周期分析表明,这些化合物诱导了MCF-7细胞在G2 / M期的细胞周期停滞。该系列中最活泼的化合物4g还抑制微管蛋白聚合,IC 50值比E7010高1.93μM。此外,通过研究对caspase-9的影响,Hoechst染色和DNA片段分析的方法表明,这些化合物通过凋亡诱导细胞死亡。对接实验表明它们与微管蛋白相互作用并有效结合。总体而言,结果表明,N -((1-苄基-1 H -1,2,3-三唑-4-基)甲基)烟酰胺骨架通过抑制微管蛋白聚合而具有抗癌特性。
